Application filed April 11, 1918. Serial No. 2273M.

To all whom may concern:

Be it known that I, Giiono'e H. DAY, a

' citizen of the United States, residing at disconnection.

Another object of the present invention is the provision of an improved manner of uniting the various parts so as to present a neat and attractive structure to rigidly and firmly unite the parts and prevent any lia bility of breakage at the joint by reinforce merit of the more brittle non-metallic member. i

A still further object ofthe invention is the provision of a joint wherein the metallic an non-metallie parts are' engaged with each other in such a manner that they will be securely and satisfactorily held against movement and at the same time provide'a finished article which will be braced or reinforced so as to prevent any liability of breakage at the oint;

With the above and other objects in view.- the invention consists in the novel features] of construction and the combination and arrangement of parts hereinafter more fully .set forth,- pointed out in the claims, and 40 shown in themccompanying drawings, in which Figure I is a side elevation of a temple constructed *in accordance with my invention:

Fig, II is a detailed enlarged elevation, parts thereof being broken away and illustrated in longitudinal section:

Fig; 111 is a similar view taken at right angles to the showing in Fig. II:

Fig. IVis a detailed enlarged view of the exterior of the joint illustrating the same in elevation: and

Fig. V is an enlarged longitudinal sectional view illustrating a'modified form of the invention,

Referring now more particularly to the drawings in which the reference characters designate the several parts throughout the views, the numeral 1 indicates the metallic side of a temple and 2 the non-iiietallic part or loop thereof, said loop being provided at its inner end with a slot or kerf as illustrated at'3, the inner. end of which is provided with an inclined wall 4 said wall terminating at one end in a transverse portion 5 which provides a suitable stop for the inner end of the metallic temple lWllQn the end of the temple is inserted within the slot or kerf 3.

The end oi the temple piece 1 which is connected with the ear loop 2 is provided with an enlargedflaltened portion 6 having formed therein a transverse opening '7 and having its outer end provided with an inclined wall coincident with the wall t and further provided with a. transverse portion 8 adapted to contact with the portion 5 to (tilt form a stop when the end 6 is inserted within the slot of the ear loop 2.

In connecting the two parts of the temple together, the end 6 of the metallic part 1 is inserted within the slot 3 of the non-metallic portion and the coengaging parts are then heated to I a certain degree and pressed tightly together so that the non-metallic portion, which is preferably Oi Xylonite, hard rubber, or other similar material; will coengage with the opening '4' and other parts of the metallic portion 1 to assist in retaining the parts against longitudinal movement. In order to firmly unite the two sections and provide for aneat appearance to the joint, a ferrule 9 is provided and adapted to'be engaged over the joint and extend upon the non-metallic portion vto a point beyond the inner end of the metallic portion 1, and formed therein is a circumferential indentation 10 which is forced therein by applying pressure to this point of the ten ruleandserves not only to me into the nonanetallie part 2 but to provide additional means whereby the two parts of the temple are firmly united. It will be noted that by applying pressure to the ferrule to form the indentation 10, it will force the material of the non-metallic portion 2 into the opening 7 as is clearly illustrated in Fig. III. From. this it will be apparent that atterthe above operation has been carried out, the two parts of the temple will be securely united against Mi l tea

ire

' modified form of the invention wherein the non-metallic part 2 is provided with a kerfed end'and the metallic part 1 is'provided with an enlarged longitudinal head portion 11 having a longitudinal slot 12 formed therethe loop 2; into the opening 12.

i in which is adapted to receive .the material of the non-metallic'part 2 when the same is pressed tightly over the end 11 so'as to securelyhold the two parts against movement,

- Furthermore, this form of the invention is providedl 'with the ferrule 9 havin the indentatiorr 10 therein which provi es additional means forforcing the mater al of It Will b foregoing (it e apparent from the scription takenin connection with the accompanying drawings that I have provided a neat and attractive temple constructed of metallic "and non-metallic parts which are securelylunite'd together and are provided with means whereby the connecting ends thereof are securelyheld against any. rela tive movementwith respect to each other.

I the ferrule is secured against movement and- I'c1aim:,;- t l. The combination with a non-metallic ear hook having .a" kerfed end, of a metallic temple side having one end engaged within j the kerfed end of the ear hook, a ferrule arranged over the oint, and means whereby at the same time forces the material of'the e'ar hook'into engagement with the end of the metallic temple side whereby to prevent relative movement of the ear hook and tem-.'

2. The combination with anon-metalllc ear hook, having a slot in one end, of a me tallic temple side, having? a slot in one end cured against movement, and at the same time forces the material of the ear hook into thereof, said slotted end being adapted to be I engaged within the slot in the ear hook to form a; joint, a ferrule arranged over the joint, and means whereby the ferruleois sethe slot atthe head of the temple side. i 3. The combination with an ear hook,hav-

ing a slot in; one, end thereof, of. a temple side, a flattened head of the temple side adapted for insertion into the slot in the ear hook, said headlhaving a slot therein, a ferrule arranged over the joint formed by the engaged ends ofthe temple sides and ear hook, and a heading formed on the interior of the ferrule for retaining the temple side and ear hook against movement.

- The combination with a non-metallic ear hook, having a slot in one end extending longitudinally of the end of the hook, of a metallic temple side, a fiat head on one end thereof having a slot therein, said head being adapted to beengaged within the slot of the ear hook and having its edges flush with the outside of the body of the ear hook, and. a ferrule arranged over the meetin ends of the temple side and ear hook an against the 'sides of the heed-to securely hol the parts against lateral-movement.

5. The combination with a non-metallic ear hook having a slot in one end extending longitudinally ofthe end of the hook, of a metallic temple side, a flat head on one end thereof havinga slotvtherein, said head being adapted to be engaged within the slot of the ear hook and having its edges flushwith the outside of the body of the ear hook, a ferrule arranged over the meeting ends of the'temple side and ear hook and bearing against the sides of the head, said ferrule being forced inwardly into the non-metallic material of the ear hook thus forcing the material into the head of the temple side to hold the joint againstmovement.

6. The combination with a non-metallic can hook having a kerfed end, of a metallic temple side having one end engaged with the kerfed end of the hook and meanswhereby the metallic member is coengaged with the non-metallic member to prevent longitudinal movement of thesame.

7. The combinationwith an ear hook, hav ing a slot in,one end thereof, of a temple side, a flattened head on the temple side adapted for insertion into the slot in the ear hook, said head havin a slot therein to receive portions of the ear 100k to retain the ear hook and temple side against longitudinal movement. i

In testimony whereof I have aflixed iny signature, in presence of two witnesses.
